Donald's, 1900 PF and Crystal Palace have been our favorites recently ... and I am pretty sure we've hit every character breakfast they offer in the past year.
We really liked Tusker House in AK for breakfast. What a selection! So much good food there...we couldn't get over it. Lots of the standard breakfast foods, but also a variety of other things too. Really, really liked it.
The only places DH requested we redo is Crystal Palace and Tusker House. The food was so good, the atmosphere was great, great character interaction and the kids had a lot of fun!
Also we do about 90% character meals. Out of the 10 ADR's I have planned to make (only CM and CRT made so far) only two are not character meals. They are Ohana dinner and T-Rex.
